How this map was built

THAI's three-class 777-300ER (internal type code 77Y), 3 aircraft (ex-BOC Aviation airframes retaining Royal First cabins), reserved for premium long-haul routes. Per-cabin counts and dimensions are published on the thaiairways.com fleet page: Royal First 8 (1-2-1 Collins "Elite Suite", 84" pitch, 23" width, 180-degree flat 78" bed, 24" screen), Royal Silk 40 (staggered 1-2-1 Stelia Solstys III, 44-46" pitch, 23" width, 180-degree flat 75-76" bed, 18" screen), Economy 255 (3-3-3 Safran 5751, 31-32" pitch, 18.1" width, 12" screen). Grid read from THAI's published cabin map (ouraircraft-77Y.png): Royal First rows 1-2 (A/E/F/K). Royal Silk Zone A rows 11-12 (8) + Zone B rows 14-21 (32) = 40; here "together" rows (centre pair together) use A/E/F/K and "apart" rows use B/D/G/J. Economy zones: Zone B rows 31-32 (18), Zone C rows 33-47 over the wing (129), Zone D rows 48-60 (108). LAYOUT PROVENANCE mixed (AUTHORING.md §5b): the airline's LOPA drawing depicts three extra Economy seats in Zone C versus its own stated Economy total of 255 (Zone C is labelled 129 but the drawing sums to ~132). The published numeric counts win: Zone C is reconciled to 129 by modelling row 47 as a left-block-only partial (ABC; the centre and right sections read as galleys on the map), matching the 255 total and the 303 grand total also stated on the fleet page and the Wikipedia fleet article. Zone D rows 48 and 59 are 2-3-2 tapers and row 60 is an outer-pairs-only last row flanking the aft lavatories. windowAlignment left "unknown" on all window seats (published map shows positions, not window alignment; no 777 engineering window grid). Recline: First/Business 180-degree flat; Economy seatback 110-120 degrees (not modelled numerically).
